ANTISEPTIC VENTILATOR.

Specification of Letters Patent.

Application filed. April 7, 1910.

Patented July 23, 1912. Serial No. 553,913.

To all whom 2'2? may concern:

Be it known that I, CHARLES F. PUTNEY, a citizen of the United States, residing at Chico, in the county of Butte and State of California, have invented a new and useful Antiseptic Ventilator, of which the following is a specification.

This invention relates to an antiseptic window ventilator and itconsists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a simple and an efiective ventilator of the character indicated which is in the form of a panel adapted to be applied to the window frame in the groove of the lower sash thereof and which contains one or more passages through which air may enter the interior of a room from the exterior of the window and the panel is provided with a block containing a chamber in which is screw threaded a cup adapted to contain the antiseptic liquid. Screens are placed over the inner ends of the air inlet through the panel and from the chamber in the said blockthe sterilized air may pass into the room.

In the accompanying drawings ;-Figure 1 is a transverse vertical sectional view of the ventilator in position in the window frame. Fig. 2 is a top plan view of the ventilator detached.

The ventilator consists of a panel 1 having preferably atone end, a chisel shaped flange 2 and provided at its other end with a recess 3 in which is located the shank 1 of an extension 5. A set screw 6 passes transversely through the innermost portion of the panel 1 and is adapted to impinge against the side of the shank at of the extension 5. From this arrangement it is apparent that by adjusting the extension 5 at the end of the panel 1 that the said panel may be elongated or contracted to fit window frames of different breadths.

The panel 1 is provided with one or more perforations or air passages 7 which are preferably inclined with their lowermost ends at the outer side of the panel. Screens 8 are located over the inner'ends of the passages 7. A casing in the form of a block 9 is secured by means of a screw or other securing device or devices to the inner side of the panel 1 and is provided in its interior with a chamber 11 with which the inner ends of the passages 7 communicate. The

block 9 is also provided with air out-lets 12 which also communicate with the chamber 11 of the said block. A ferrule or a number of ferrules 13 are screw threaded in the bottom of the block 9 and cups 1 1 are screw threaded in the said ferrule 13 or ferrules.

In practice the cup 1a is removed from the ferrule 13 and an antiseptic liquid or disinfectant is placed in the said cup, and the said cup is screwed back in position in the ferrule 13. Thus it will be seen that when the panel 1 is in position in the window frame that air may enter the chamber 11 through the passages 7 and in the said chamber will commingle with the vapor of the liquid contained within the cup let and will carry the particles of the liquid through the outlet 12 into the room. In this manner the atmosphere of the room is sterilized and when the ventilator is used in hospitals or sick rooms the chance of spread of infectious diseases is reduced to a minimum. By reason of the fact that the screens 8 are located over the inner ends of the passages 7 the ingress and exit of insects from the room is prevented and thus the chance of spread of the disease is further minimized. Furthermore it will be seen that the parts of the ventilator are so arranged that ventilation without an attending draft is attained.

The panel 1 is adapted to rest upon the window ledge 15, the upper edge of the pane-l 1 being engaged by the lower edge of the window-sash 16. .The inner face of the panel 1 is flush with the inner face of the sash 16. Noting the point at which the reference character 17 is applied in Fig. 1, it will be observed that the casing 9 is ex tended upwardly above the panel 1, to en-- gage the inner face of the sash 16, thereby to prevent the panel from falling outwardly. The opening 12 in the top of the casing 9 is vertically alined with the opening in which the cup 14; is removably mounted. Therefore,

the volatile contents of the cup 14 will pass directly out of the opening 12, irrespective of whether or not there is a draft through the passage 7 and through the opening 12.

Having described the invention what I claim as new and desire to secure by Letters Patent is In a device of the class described,'a panel adapted to rest upon a window ledge and to be engaged by the lower edge of a sash; a casing secured to the inner face of the panel and extended upwardly above the panel, to engage the inner face of the sash, thereby to hold the inner face of the panel flush with the inner face of the sash and prevent the panel from falling outwardly, there being a chamber in the casing, and vertically alined upper and lower openin 's through the top and bottom of the casing, respectively, the panel having an air passage therethrough, communicating with the chamber between the openings; and an open cup removably mounted in the lower opening, the vertically alined relation of the upper and lower openings permitting the volatile contents of the cup to pass directly out of the upper opening, irrespective of the draft through the passage and through the upper opening.

In testimony that I claim the foregoing as my own, I have hereto a'llixed my signature in the presence of two witnesses.

CHARLES F. PUTNEY.
